David Kennedy CHE 235 Lab 10/30/14 Scale-up Synthesis and Characterization of Butyl 2-Cyano-3-(3‚5-dichloro-phenyl)-2-propenoate‚ TSE Project #131 Introduction: This report describes the steps taken to create the scale-up of targeted trisubstituted ethylene‚ Butyl 2-Cyano-3-(3‚5-dichloro-phenyl)-2-propenoate compound (#131)‚ and also the characterization methods deployed to the results. This report serves as a critical step in the overall objective of the project; the synthesis of the copolymer. The

Their blood is almost transparent because of the lack of red blood cells‚ and they are the only vertebrate that does not have circulating hemoglobin. Those organisms are referred to as Ice fish‚ and they are one of the unique organism that live in Southern Ocean around Antarctica and Southern South America‚ where water temperatures remain relatively stable. Hemoglobin is a protein within mammalian red blood cells that transports oxygen for delivery to tissues throughout the body. Having red blood

I have used the scientific method in my case study to prove my hypothesis‚ if a plant is grown in light it will grow faster than a plant grown in the dark. To conduct my experiment‚ you will need lima beans‚ potting soil‚ and styrofoam cups. First‚ put three inches of potting soil into each styrofoam cup. Then plant the lima bean seed about one inch below the surface of the soil. Next add three tablespoons of water to each cup. Put one cup in a window seal or where there will be bright light. Place

11. Account for the fact that ethylene glycol (HOCH2CH2OH) is less viscous than glycerine (HOCH2CHOHCH2OH)‚ but more viscous than ethyl alcohol (CH3CH2OH). 20. Consider the following substances: sodium fl uoride (NaF)‚ chlorine monofl uoride (ClF)‚ hydrogen fl uoride (HF)‚ and fluorine (F2 ). (a) What type of particles does each substance have? (b) What type of intermolecular attractive forces hold the particles together in each substance? The table below lists the melting point (mp)‚

of nickel was produced. It was then followed by electrodeposition of nickel. Through successive casting and curing of polymers a positive die of epoxy was created from this negative die. Together‚ both of them constituted the mould. Next‚ a poly(ethylene terephthalate) (PET) sheet was used to spincoat on one side of the quarter-wave Bragg stack reflector comprising alternating layers of poly(vinyl cinnamate) and poly(acrylic acid). This is done so as to make sure that the PET sheet acquired a green

Product strategic: As we all know‚ Mazda is a part of Ford’s core strategy. We think Ford needs to develop the fair price cars which can suitable for more people. As a result‚ Ford may not attempt to market a global luxury brand. They need to change the technology they used. Use more modern science and technology to improve their products quality. As for new product‚ they present cars which use less fuel than before‚ what’s more‚ they present cars which use the electricity and then will eliminate
